XML Formatter
Use our XML formatter to clean up indentation and spacing. Paste code, format it instantly, and copy the result for your project. Great for quick QA.

What this does
So you have got XML that came as a single unbroken line, an API response, a config file, or a feed, and picking out where one element ends and the next begins is a chore. This lays it out. Paste your XML, click Format, and the nested elements come back indented so the structure reads clearly.
How to use it
- Paste your XML into the box.
- Click Format.
- Copy the formatted XML with the Copy button.
How it works
The tool runs your XML through a beautifier that re-indents the markup, putting elements on their own lines and nesting child elements under their parents. The result follows the shape of your document, so a flat string of tags becomes a readable tree. All of this happens on your own machine, in the browser, so the XML you paste is not sent anywhere.
Why indenting XML helps
XML earns its keep in places where structure matters: configuration, data exchange, document formats. That structure is exactly what gets lost when the markup is squashed onto one line. Indented properly, a parent element and its children line up so you can see at a glance how deep the nesting goes and where each section sits, which makes a config quicker to edit and a response easier to debug.
Keep in mind that this handles layout. It works best with well formed XML, but it is not a strict XML validator.
Questions people ask
Does formatting change my XML data?
No. It only adds indentation and line breaks. The elements, attributes, and values stay exactly as they were.
Why did it report an error?
The tool expects well formed XML, so a problem like an unclosed tag can stop it. Fixing the markup usually clears it.
Does it check my XML against a schema?
No. It formats the layout only. Validating against a schema or DTD is a separate task it does not perform.
Is my XML uploaded?
No. Everything runs in your browser, so nothing you paste leaves your machine.
